CYCLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 636,740, dated November 14, 1899.

Application filed October 29, 18 98, $erial No. 694,981. (No model.)

To on whom it may concern:

Be it known that I, J ULIO DANIEL AMENA- BAR, a subject of the Queen of Great Britain, residing at- Wolverhampton, in the county of Stafford, England, have invented certain Improvements in Cycle-Locks, of which the following is a specification.

My invention relates to cycle-locks.

It has for its objects, first, to provide a temporary lock for the steering-gear; second, to lock the steering, so that only a person provided with the key can unlock it; third, to provide a lock for the brake, and, fourth, to provide a lock for the lamp.

With these objects in View my invention consists of the construction and arrangement of-parts hereinafter described, and specifically pointed out in the claims.

In the accompanying drawings, Figure I is a top side plan, and Fig. II is an under side plan, of the device. Fig. III is a side elevation of the device applied toa diamond-framed safety-bicycle and shows the device out of action. Fig. IV is a similar view of the device applied to a ladys bicycle and shows the device in action. Fig. V is an elevation of the lamp-catch.

Like numerals indicate like parts in all the figures.

The hinged plate 2 is provided with a hole 3, so that it may be attached to the head 6 under the lock-nut 5 in the position usually occupied by the lamp-bracket, which it may be adapted to replace. To the plate 2 is hinged at 4 a fork 7, which normally lies turned over forward onto the said plate, as shown in Fig. III, where it is preferably retained by a light spring catch 8, so that it cannot fall back into action accidentally.

The device is provided with a spring tumbler-lock of any suitable construction, which is brought into action by turning the fork right down, and then holds the fork thus until the lock is undone. For example, the lock may be contained in a case 11, fixed to the back of the fork 7, and may be adapted to engage by a spring action with the studs 12 on the plate 2 when the fork is carried beyond the position shown in dotted lines in Fig. IV into the position shown in full lines in the same figure. The fork may be released by undoing the lock Witha suitable key.

Secured to the portion of the plunger-rod 15 adjacent to the front or lamp-bracket part 16 of the plate 2 is a toothed rack 17. This rack is preferably secured on the plunger-rod by a collar 18 at each end, through which the said rod passes, and by set-screws 19, threaded through the said collars 18,preferably directed from the back thereof and inserted before the said rod is attached to the machine, so that when in position the screws 19 are rendered inaccessible by reason of the obstruction offered by the head 6 and the rack cannot be fraudulently loosened on the rod 15. A sleeve 20 may be introduced between the rack 17 and the tubular part 31 of the plunger to prevent fraudulent shortening of the plunger as a whole. The plunger and rack normally pass freely through the aperture 22 in the plate 2, which aperture is made large enough to allow of considerable variation in the size of the plunger-rod and its distance from the head 6. On the said plate, and preferably on the under side thereof, is pivoted at 14 the above-mentioned lever 21, the front end 23 of which is adapted to engage with the above-mentioned rack 17 when forced in the direction'thereof against the action of a suitable spring, such as the compression-spring 24, which is threaded on the oscillating guide-rod 25, pivoted to the lever 21 and passing through the eye 26,

fixed to the plate 2. The other end of the lever is formed with an incline or cam 27, the face being highest toward the outer edge of the plate 2 and lowest toward the center line of the said plate, the said cam being adapted to be engaged by the fork or a part, such as the case 11 of the lock, attached thereto. A bridge-guide 28 may be employed to support and act as a stop for the front end of the lever 21. The stud 29 enters between the jaws of the split clamp 30 and prevents the plate 2 rotating.

The catch 32 is either hooked into the socket 33 of the lamp by its bent upper end 34, as shown in Fig. III, or it may be fixed thereto. The lower end of the catch passes down through the aperture22 and is provided with a projection 35, which is adapted to be engaged by the front end 23 of the lever 21 at the same time as the said lever engages the rack 17 on the plunger-rod 15. p

The apparatus is employed as follows:

ICO

'When the velocipede is to be used, the fork 7 is turned back on the plate 2, as shown in Fig. III. To temporarily lock the steering only, the fork 7 is turned down on its hinge 4 so as to span the top tube 9 of a diamond frame, or in the case of a ladys safety-bicycle it will span the stud 10, clipped to the head 6 for the purpose, (and preferably taking the form of a hollow case,) as shown in dotted lines in Fig. IV. To look the steering so that only a person provided with the key can unlock it, the fork is turned farther into the position shown in full lines in Fig. IV. This also secures the lamp by causing the front end 23 of the lever 21 to project over the part 35 of the catch 32, so that the lamp cannot be lifted off the bracket 16. If it be desired to lock the brake on, as well as lock the steering, the brake is held on by hand, while the fork 'Z is passed from the dotted-line position to the full-line position in Fig. IV, so that the corner of the lock nearest to the cam 27 strikes the face thereof and then forces the cam back and with it the rear end of the lever. This causes the front end 23 of the lever to engage with the rack 17, and when the lock catches the parts are held in position, and the brake is consequently locked on. The steering is released by undoing the lock and turning the fork back to its original position, Fig. III. As the casing 11 leaves the cam 27 the spring 24 carries the lever 21 out of engagement with the rack 17 and the brake resumes its off position. The prongs of the fork 7 may be provided with rubber sleeves or the like to prevent chafing the fixed part of the machine.
